HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 457, 264, 53 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 457, 264, 53 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 457, 264, 53 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 457, 264, 53 is 1.

HCF(457, 264, 53) = 1

HCF of 457, 264, 53 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 457, 264, 53 is 1.

Highest Common Factor of 457,264,53 using Euclid's algorithm

Highest Common Factor of 457,264,53 is 1

Step 1: Since 457 > 264, we apply the division lemma to 457 and 264, to get

457 = 264 x 1 + 193

Step 2: Since the reminder 264 ≠ 0, we apply division lemma to 193 and 264, to get

264 = 193 x 1 + 71

Step 3: We consider the new divisor 193 and the new remainder 71, and apply the division lemma to get

193 = 71 x 2 + 51

We consider the new divisor 71 and the new remainder 51,and apply the division lemma to get

71 = 51 x 1 + 20

We consider the new divisor 51 and the new remainder 20,and apply the division lemma to get

51 = 20 x 2 + 11

We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get

20 = 11 x 1 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 457 and 264 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(51,20) = HCF(71,51) = HCF(193,71) = HCF(264,193) = HCF(457,264) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 53 > 1, we apply the division lemma to 53 and 1, to get

53 = 1 x 53 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 53 is 1

Notice that 1 = HCF(53,1) .
